(a) 

In the above reaction,
ketone group is replaced by =N--O and thus form the diagram as above. It is a type of substitution reaction. In this reaction, H⁺ is taken as reagent because through hydrolysis it is done.

(b) 

In the above reaction,
Ethyl Benzene reacts with KMnO₄-KOH in the heat and forms potassium benzoate as an intermediate and through hydrolysis as shown in above diagram makes benzoic acid as a product.

(c) 

In the above reaction,
Phthalic acid is heated with Thionyl Chloride and through dehydration of phthalic acid it forms Phthaloyl Chloride as a final product.

(d)

In the above reaction,
Methylenecyclohexane reacts with BH₃, as BH₃ is an electron-deficient atom. So, it can act as an electrophile and then it coordination compounds in between and finally it forms Cyclohexaldyhide as a final product. 

(e)

In the above reaction,
Benzene reacts with Benzoyl chloride in the presence of Anhyd. AlCl₃ as a reagent it forms Benzophenone as a final product and also HCl gas produced.
